Android still doesn't come close to iOS in terms of smoothness of the UI....this is coming from a GNex w/ Jellybean and 4S user. Though Jellybean has made significant inroads compared to ICS in the smoothness category.

I just never liked the Galaxy series form factor. Too often I'm trying to navigate one handed and it's uncomfortable to stretch the thumb to pull down the drawer for my toggles. I wonder which manufacturer can balance larger screen size with small form factor and find the perfect balance.
